@mashif Understood and agree.
This is why it is so difficult to get new entrants into this hobby; we keep making it more complicated (and expensive) for newbies to put together a system (including room) that is acceptable to 'us" and not subject to outright ridicule and scorn.
I have no idea what this means. We are having a discussion. If some of it goes above a new entrants' head, well that's not our responsibility. This is not a textbook or a "how to" blog. If some new person needs an explanation, they can ask for it. They're not children.
